With increasing sized constellations being used in conjunction with spatial multiplexing MIMO systems, the complexity of even polynomial-time detection methods can be computationally burdensome. In comparison, linear detection methods increase in complexity linearly proportional to the constellation size and number of transmit antennas used. However, basic linear detection strategies suffer significantly from noise enhancement due to non-orthogonality of the channel matrix. Lattice-reduction-aided detection (LRAD) has been identified as a way of improving the performance of linear detection strategies.
